Declaring variables means naming the variable and specifying their data types, that is declaration statements establish our project’s variables and constants give them names, and specify the data type they will hold.

To hold the internal data of our class create private variables in the general declaration of the class modules. Then we have to deign which properties we want to write access. We can decide these things using property get and property let procedures.

(Dynamic-linked library) In programming, a type of LIBRARY file that becomes LINKED to a program that uses it only temporarily when the program is loaded into memory or executed, rather than being permanently built-in when the program is COMPILED. The same DLL may therefore be shared by many different programs, rather than each program having to contain its own copy; this saves on memory usage and potentially simplifies the updating of programs.

This phrase has two meanings. Compile time can refer to how long it takes to compile a given program (see the entry above). The compile time for a program depends on how long and complicated the program is, the speed of the computer, and the quality of the compiler.
